To all whom it may concern:

Be it known that l, HENRY G. Etienne, a citizen of the United States, residing'at Chicago, in the county of Cook and State of illinois, have invented certain new andv ment in the operation ot' the device in se/ curing a greaterl tri-ctional contact between the stationary anti-creepervdevice andthe rail to which it is applied.

As will be apparent from the following description and claims, together with the drawing, my improved device not only grips the opposite edges of the rail-base, but also secures aqlirm frictional grip between thev under surface of the rail base and the coacting part of the anti-creeper structure.

.ln the drawings Figure 1 is a cross section of a rai-l with my improved anti-creeper applied thereto. Fig. :2 is a plan view of the same. Fig. 3 is a side elevation look-ingl from the lett of' Figs.' i and 2. 3, 3' and 3 are sections taken respectively on the like numbered lines appearing upon `Fig. 3.- Fig. et is a perspective view showing the rail and the elements oi the anti-creeper in perspective, the parts being partially separated, but arranged in substantially their correct relation to one another. Fig. .5 is an elevation view of the -main member of another embodiment ot my invent-ion. Figs. (i and 7 are plan and end views respectively of the main member shown in Fig. 5. Fig. 8 is a plan view of the wedge member adapted to coact lwith the mainlv member shown in Fig. 5. Figs. 9 and l0 are views of the opposite ends of the wedge shown `in l4` ig. 8. F ig. ll is a side elevation of the wedge member shown in Figs. 8, 9 and l0.

Fig. l2 is a perspective View et the wedge' member shown in Figs.' 8 to '1l-,L 13. is an elevation transversely-of the rail, which .is in section of the assembled structure shown in Figs. 5 to 12. Fig. lll is a plan view of the structure shown in Fig. 13.

lWhile my invention is not restricted to either of the speciiic embodiments illustrated and described in this application7 l have selected the two forms referred to as those preferred by me at thls time and as forming a basis lfor an explanation ot the principle of my invention. i Referring first to the embodiment of the invention illustrated in Figs. 1 to 4l, the structure consists essentially of two elements, a main member designated A and a `wedge I4member designated B. The main member A. is formed @at one end withan upturned lip or shoulder l which may be inturned, as shown at 2, to embrace the edge and part of the upper surface of the rail base. rlhe main member A is adapted to 'eX-tend beneath and in contact with the lower surface of the base o the raill and projects beyond the opposite edge of the rail base. At theend opposite the lip 1 the main member A is rovided with an ,upstanding shoulder 4f, t e inner substantially vertical tace 5 of which converges toward the adjacent edge of the rail base in the directionof an adjacent tie 7, against which the downwardly extendingI abutment 6 at the opposite end ot the main member is adapted to bear. The under side ot the end of the member A opposite the lip or shoulder l--2 is provided with a surface 8, which inclines downwardly toward the adjacent tie 7. rthis sloping `part of the under side ot the main member preferably also has an inclination in an upward direction from the end on, said membenas shown in the drawings, and at the inner limit of said sloping or inclined surface 8 l preferably` .Patented dan. 6, 19ML.

provide the main member with downwardly extendinglugs 9. 'The wedge end ofthe mainmember A, that is, the end opposite the lip or shoulderl-f, is provided upon its under surface with a notch '10 extending endwise of said member, said notch .serving to remove the central portion of the depending part of Ithe end member upon which the inclined surface 8 is formed. l have illustrated the main member A as provided l upon its under and outer surface with strengthening ribs l1 and have also shown the main member A of such form as to eX- tend across the -rail base at er1-inclination thereto, as clearly illustrated in Fig. 2. The

' between the slots 14,'14,

ward the rail in the direction Awedge member B, adapted to coact with the wedge end of the main member A, is best illustrated in its entirety at' the left of Fig. 4 Where the parts are shown in perspective.

vIn this particular embodiment of the invention the wedge member is provided with a central slot or opening 12 and is adapted to be passed over and to embrace the wedge end of the main member. The outer side of the portion of the wedge member B above the slot 12 is Vformed with a surface 5 which, when the parts are assembled, converges toof the adjacent tie 7,the surface 5 upon the wedge member being adapted to coact with the surface 5 upon the shoulder 4 of the main member, thereby serving to wedge the upper part of the wedge member B between the shoulder of the main member and the adjacent edge of the rail base when said wedge member is driven or otherwise impelled toward the tie 7. The upper part of the wedge member B is formed on its inner side with a lip 13 adapted to overlie the edge of the base of the rail 3. The'lower part vof the.

lower part of the wedge member B belowA the slot 12 is notched upon its upper surface, as indicated at 14 and 14.

In assembling the device, the main member A is placed under the rail with its' lip or shoulder 1-2 embracing one edge of the base thereof .and with the abutment 6 against one of the ties, the device being placed upon that side ofthe tie from which the greatest volume of traffic moves.

trated in Fig. 4 and the proximity of the device to the adjacent tie is indicated in Figs. 2 and 3. The wedge member B is then mounted upon the wedge end of the main member, the'slot 12 in the wedge member being of sutlicient depth verticallyto receive the end of the main member when thenotch 10 in the lower side of the main member is made to register with the part of the wedge member which projects upwardly at'which time the notches 1414 register with the downwardly projecting portions 15 of the main member at the si es of the notch 10. After the wedge member B is placed over the wedge end of the main member, it is lowered yso that the upper part of the wedge member above the slot 12 therein lies between the shoulder 4 ofthe main lmember This j position of the main member is well illus! member. The coaction between the surfaces 5, 5 causes the upper part of the wedge member to exert transverse pressure upon the edge of the rail base, thereby firmly gripping the rail between said wedge member and the lip or shoulder 1-2 at the opposite end of the main member. The coaction between the surfaces 8, 8 of the main memberand wedge member, when the wedge member is driven toward the tie or otherwise impelled in that direction, has the effect of drawing the main member upward against the under surface of the rait base by reason of the fact that the lip 13 of the wedge member overlies the edge of the rail base, while the movement of the wedge member toward the tie forces thel main member upwardly-by reason of the inclination of the coacting surfaces 8, 8. The depending lugs 9 upon the main member serve to prevent the wedge member from tilting in the direction of the arrow 16, appearing in Fig. 1, and the inclination of the surfaces 8, 8 transversely of the rail serves to'prevent the wedge member from tilting inthe opposite direction.

In the initial assemblage of the device, as above stated, the abutment Gupon the main member bears against the adjacent tie,

toward which tratlic is moving and the wedgemember is forcibly driven to its seat, thereby insuring a gripping of the opposite edges of the rail base between the wedge member and the opposite end of the main member and further securing a firm hold on the rail by reason of the pressure set up between the upper surface of the main member andl the lower surface of the rail base. Any tendency of the rail to creep in practice would, by reason of the frictional grip thereon exercised, by the wedge, tend to force the wedge still farther to its seat,

.thereby more rmly gripping the rail, and

furthermore, any tendency of the rail t0 creep would necessarily result in a tendencyl to rotate the main member A by reason of the frictional grip between the main member and rail base, and the fact that the abutment of the main member holds that end of the main member stationary by reason of its bearing against the tie.A Any ls'uch 7tendency to rotation on the 4part of the main member would also tend to more securely lzo engage the edge of the rail base, and the other end of said main member having an upwardly extending shoulder converging in a horizontal plane with the opposite edge of the rail base toward said tie, said .last mentioned end of said main member having also a downwardly projecting lug, the lower surface of which has a longitudinally inclined surface, and a slotted'wedge member adapted to embrace the last n'amed end of said main member, a4 lug projecting upwardly from -the lower wall of the slot in said wedge, the upper surface of said lug having a longitudinally inclined surface corresponding to the inclination of the down` wardly extending lug on the main member, the upper part of said wedge member above the slot therein having an inclined outer side surface adapted to coact with ,theinclined lupwardly extending shoulder on the main member and adapted on its inner-side to engage the adjacent part of the rail base.

4. An anti-Creeper for railro-ad rails comprising a main member adapted to underlie the base of a rail and to bear against a tie, one end of said main member having an upwardly extending part adapted to directly engage the edgel of the rail base, and the other end of' said main member having an upwardly extending shoulder converging in a horizontal plane with the opposite edge of the rail base toward said tie, said last mentioned endvof saidimain member having also downwardly projecting lugs, the lower surfaces of which incline longitudinally, a

'slotted wedge member adapted to embrace the last Vnamed end of said main member, lugs projecting-upwardly from the lower wall of the slot in said wedge, the upper surfaces of said lugs inclining longitudinally corresponding 'to the inclination of the downwardly extending lugs in the main member, the upper'part of said wedge member above the slot therein having an inclined outer side surface adapted to coact with the inclined upwardly extending shoulder on the main member and adapted on itsinner side to engage-the adjacent part of the rail base.

5. An anti-Creeper for railroad rails com-A prising a main member adapted to underlie the base of a railand to bear against a tie, one end `of said main member having an upwardly'` extending part adapted to directly also downwardly projecting lugs, the lower named end ofsai'd main member, lugs pro-` jecting upwardly from the lower wall of the slot in said wedge, the upper surfaces of said lugs inclining longitudinally and transversely corresponding to the inclination of the downwardly extending lugs on the main member, the upper part of said wedge ineinber above the -slot therein having an .inclined outer side surface adapted to coact with the inclined upwardly extending shoulder on the main member and adapted on its inner side to engage the adjacent part of the l rail base.

6. In a device of the class described, a rail, a main member having a jaw at one end embracing one edge of the rail base, saidmain 1member extending beneath said rail to the opposite edge thereof, a wedge mem-- ber engaging the upper-,side ofthe opposite edge of the rail base and also extending beneath a part of said main member, said main and .wedge members having two pairs of coacting lwedge surfaces, both pairs being inclined longitudinally of said rail.

7. An antiecreeper for railroad rails coinprising a member adapted'to'underlie the base of a rail, one end of said memberk hav ing an upwardly extending part adapted -to directly engage the edge of the rail base and the other end of said member having an up# wardly extending shoulder converging in a horizontal pla-ne with the o-pposite edge of -the rail base toward said tie, said last mentioned end of said member also having a surface inclining downwardly toward said tie, and a wedge member having one part coacting with said upwardly extending shoul-v der of said lirst-n-amed member and the ad` jacent edge of the rail -base and having a'.
